CHAPTER VIII. 
MOSSES AND LIVERWORTS. 
By 
G. H. GRAHAM, M.A. 
Tue Geological Survey of Canada has published 
comprehensive lists of the Bryophyta—Part VI on 
the Mosses, VII including the Liverworts—and these 
contain a good representation of Southern Ontario 
forms, and especially of the Lake Erie and Eastern 
Lake Ontario Districts. As Toronto lies between the 
two it probably comprises in its flora a majority of 
the species found in both. If this be the case the 
following list contains little more than a third of the 
mosses and liverworts growing within easy collecting 
distance of the city. 
The author is under special obligation to Pro- 
fessor Coleman for the list of interglacial mosses 
from Scarborough and the Don. 
Hepaticar—Liverworts.
